Embodiment
As shown in Figure 1 and Figure 2, the digital electronic special cunning of frequency conversion drive reducing optical cable of one kind provided by the utility model
Car, including：
A pair of risers 6, in arranged for interval, respectively in C fonts；
Multiple rollers 9, the multiple roller 9 respectively by a roller shaft 7 be installed in rotation on the pair of riser 6 it
Between, and the multiple roller 9 arranges ovalisation, to form elliptic pulley group；Set between the roller 9 and roller shaft 7
There is bearing 20, to improve rotation flexibility；
Suspension ring 1, it is connected with the pair of riser 6；Wherein, the suspension ring 1 are fixed on a boatswain chair 101, the boatswain chair
101 are fixed between one end of a pair of connecting plates 2,3, and a cunning is also folded between the other end of the pair of connecting plate 2,3
Car bearing pin 12, the coaster bearing pin 12 are provided with bushing 11, the bushing 11 through the pair of riser 6 and with it is the pair of
Riser 6 is rotatably coupled；A guide shaft 5 is also equipped between the pair of connecting plate 2,3, is cased with leading on the guide shaft 5
Roller 4, the deflector roll 4 are located at the outer circumferential side of the elliptic pulley group, optical cable are limited into the deflector roll 4 and the roller
Between 9, prevent optical cable from beating.
Wherein, through type lubricating cup 23 is provided with the coaster bearing pin 12, for providing lubricating oil to the bushing 11.
In addition, as shown in Figure 1, Figure 3, deviate certain angle (such as 43 degree) place in the both sides of suspension ring 1 and be also respectively provided with a limit
